Airtac MAC Stainless Steel Mini Air Cylinder MAC63X140SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC63X140SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø63mm bore and 140mm stroke, 1/4" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X140SCM
Rated to 317.7 kgf theoretical at 1.0 MPa, the MAC63X140SCM is the heavy hitter of the round-body MAC line, with a 140 mm stroke for deep presses and long transfers. Its rolled stainless barrel and 20 um hard-chrome rod resist the coolant mist and splash that ruin painted minis, and double-acting air with adjustable cushions at both ends keeps every stop controlled across the 30-800 mm/s speed range.
At 0.5 MPa the bore produces 1557.9 N push and 1457.4 N pull; at 0.7 MPa, 2181.0 N. Sized for real work that is about 935 N of push - enough to lift roughly 79 kg vertically with a 2:1 margin. The CM round-end back cover and the standard piston magnet (ready for CMSG, DMSG or EMSG switches) come as supplied, not as add-cost options.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1559 N | 1458 N |
| 0.7 MPa | 2182 N | 2041 N |
| Max (@1.0 MPa) | 318 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X140SCM Is Used
Bench punch station
Drives a small punch die through 2 mm aluminium bracket blanks; 1557.9 N at 0.5 MPa shears cleanly and the 140 mm stroke clears deep workpieces under the nose.
Pallet carton pusher
Sweeps formed cartons off a palletizing sweep table; 935 N of usable push moves full layers square while the cushioned stop keeps stacks tidy at line speed.
Sluice gate actuator
Opens a slide gate on a wastewater screening channel, where the stainless round barrel stands up to constant splash and the magnet feeds gate-open signals back to SCADA.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC63X140SCM the Right Cylinder?
Against the 50 mm bore (981.3 N push at 0.5 MPa) this cylinder delivers about 60 percent more push, and 63 mm is where the MAC cushioned series peaks. Long strokes like 140 mm magnify side load at the rod bushing, so guide the load on slides or outriggers rather than cantilevering it off the rod; the M14x1.5 rod thread and 1/4" ports keep plumbing straightforward. A plain MAC drifts when de-energised - the cushion is not a brake - so specify a rod lock or pilot check valve for held positions, and use FA, LB or SDB brackets plus I/Y knuckles for the mounting.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAC Stainless Steel Mini Air Cylinder MAC63X140SCM FAQ
No - it is a plain double-acting cylinder, so with air vented or the valve centred the piston drifts freely, and the variable air cushion only softens end-of-stroke impact, it never locks. For parked loads add a rod lock or a pilot check valve in the line; the bore still delivers 1557.9 N push and 1457.4 N pull at 0.5 MPa, 2181.0 N push at 0.7 MPa, and up to 317.7 kgf theoretical at 1.0 MPa.
The body is a riveted stainless-steel round barrel with a hard-chrome plated carbon-steel rod and aluminium covers - no painted surfaces to bubble or flake. Pair that with 40 um filtered air at 0.15-1.0 MPa (22-145 psi) and periodic cushion checks, and it shrugs off washdown, coolant mist and outdoor exposure.
